If I have a JLabel with <u> tag, such as <html><u>text</u>, with WindowsLookAndFeel and WindowsClassicLookAndFeel the underline is not rendered. I have reported this bug.
If no Look and Feel is set, or with Nimbus, all correct.
I know I can set the font attributes of the JLabel, but what if I only want to render one part of the text?
EDIT: I have tested and found that it is a bug of MigLayout combined with UIManger font setting.
Try the code: comment out anyone of UIManager.put("Label.font") or setLayout(MigLayout(xxx)) will solve the problem, but if they are both present, the line is not shown. I changed the title of question to describe it better. Now I see it has nothing to do with L&F, because Nimbus neither render the line.
The effect is:
